TDS on large cash withdrawals requires banks and post offices to deduct tax when aggregate cash limits are breached. Section 194N requires specified banking companies, co operative banking societies and post offices to deduct TDS on large aggregate cash withdrawals by a recipient when prescribed thresholds are exceeded; rates differ based on whether the recipient filed returns for three relevant years and special threshold treatment applies to co operative societies. The provision exempts payments to the Government and specified banking agents, white label ATM cash replenishment accounts, Full Fledged Money Changers and authorised dealers subject to certification and compliance, and permits Central Government notifications in consultation with the Reserve Bank. Rule 37BA directs credit of tax to the person whose account was debited for the assessment year relevant to the previous year.
